The RCV-5000 listed above handles this by using specific firmware files specifically programmed for the piece of equipment.

The RS232 Code converter must be able to handle these different baud rates and command protocols. Typical baud rates range from 1200 baud all the way up to 115200 baud. They all vary in baud rates, and communication protocols (9600, 8N1 or 19200, 8O1 etc.). Some of the RS232 code strings are ASCII, some are HEX and some are a combination of both. These RS232 codes are sometimes called data strings, command strings, command data or similar. Celadon sells low volume remote controls that can be used for this purpose.Įach piece of equipment, be it a LG TV, a Runco Projector, or a Key Digital Matrix Switch, has a unique set of RS232 codes to access specific functions on the equipment.
Contact the infrared to RS232 code converter RCV-5000 manufacturer Celadon to see how this can be done. Off-the-shelf remote controls can also be used to control the device. LIN (Niles) format and can easily be loaded into one of these manufacturers remotes, or imported into other remotes that can handle these formats.Įach infrared code is mapped to a specific RS232 code function for the piece of equipment being controlled. The RS232 code device mentioned above, the RCV-5000, receives unique infrared codes that have been specifically created for it. Please check out the infrared to RS232 converter from Celadon, the RCV-5000. There is one such device on the market which handles these tasks very well. The RS232 converter must be programmed or course to not only see the correct infrared codes, but also send out the correct RS232 codes for the specific piece of equipment (since all equipment has different RS232 codes). This special infrared receiver will see infrared codes and then in response, send out RS232 codes. The next obvious question is what if you don't want to use a computer to control your equipment? Or, how do you get the programmable remote to actually send out the RS232 codes? Well, the answer to both these questions lies in a infrared to RS232 converter. Want to get to Volume 47? For some equipment there is a specific RS232 code for that volume. Some equipment has RS232 codes for specific volume levels. The many RS232 codes available for a piece of equipment will depend not only on the features of the device (a Matrix Switcher will not have volume control RS232 codes for example), but also depend on what the manufacturer decided to include. If these RS232 codes are now added to a macro sequence on the programmable remote, the device will always be switched to the correct Input. So, Video 1 will have a unique RS232 code string, and Video 2 will have another unique RS232 code string.
The RS232 codes provide an easy way to go directly to a specific input, since most manufacturers create unique RS232 codes for specific functions on the equipment. Sometimes 'Input' must be pressed 3 times, sometimes 4 or more. It all depends on the mode where the equipment starts off. If someone is using a high end remote control with macro sequence programming features and needs to make sure the equipment is switched to Video 1 for a specific macro, there becomes the problem of how many times does one program the 'Input' button to get to RGB1? A single button on the remote will loop through HDMI1, HDMI2, HDMI3, HDMI4, RGB1, RGB2, Component 1, Component 2, Video 1, Video 2, S-Video etc. Also, many remote controls are set up such that one button will loop through a sequence of related features.
Remote controls have a limited number of buttons, so not all functions are included. However, there are many more functions which the user may want access to that are not included on the remote control. The remote control is used to activate many of the most common functions on the electronic device. Why might this be beneficial? Typically these consumer electronic devices are sold with an infrared remote control. For most devices, the RS232 port allows a user to control the device directly from a host computer or other device acting as a host computer.
